It is better to follow out a plan consistently even if it isn't the best one than to play without a plan at all. The worst thing is to wander about aimlessly.  -  Alexander Kotov

Here continues my first attempt at a Stokyo Position: (part 1)



Position after 12. Qg3 f5

Some options for white in this position:


A. Qxe5

B. Nxd5
C. O-O

D. b3
E. Be2


A. 13. Qxe5 fxe4, followed by Bxe4 or Nxe4.

14. Nxe4. Material is equal and I estimate the position is =. [  -+ ]


14… Bc5 15. O-O and white holds the position. = [ -+ ]


.... 15. Nxc5 Re8 -/+ [ -+ black will be up a pawn … better mobility? ]


14. … Bf5 15. O-O = [  -+  ]


15. Ng3 Bd6 16. Qd4 [  16. Qxf5 Rxf5 17. Nxf5 best ] Re8+ 17. Kf1


… 17. Ne2 Be5 [ 17. … Bxd3 18. cxd3 Nf4 ] 18. Qa4


… 18. Qc5 Bxd3 19. cxd3 Nf4 20. O-O [  20. Kf1 best, 20. … Nxe2 ] Nxe2+ -+


18… Bxd3 19. cxd3 Nf4 [ Bd6 or Bc7 better ] 20. Nxf4 Bxb2+ 21. Ne2

21. Kf1 [  21.      Kd1 best ] Bxa1)

21… Bxa1 -+

21 … Qe7 might be better, threatening the mate first [ 21. … Bxa1 best, 21. … Qxd3 better than Qe7 ]


15. Nc3 Bd6 16. Qd4 Re8+ [ forgot to evaluate at this point; -+ ]


[ 15. b3 about the same as O-O -+ ]


14. … Nb4 15. Qc3 Nxd3 = [ -+ ]


… 15. Be2 Nxc2+ -+


… 15. O-O [  best  ] Nxd3 16. cxd3 Ba6 17.Re1 Bxd3 -/+ [  -+ ]


14. … Rf5 [  best  ] 15. Qd4 +/= [  -+, best 15. Qg3 Bh4 16. Qd6 Bxf2+ 17. Kd1 Qe8 ]


14. … Bb7 = [ -+ ]


14. … Nb7 15. Bc4 += [  -+ ]


14. Bxe4 Bc5 [ 14. … Nf4 best. Bd6 and Nf6 also good. -+ ] 15. O-O = [ -+ ]

15. d4 (as in the referenced game above) Re8 16. Qg3 Nxc3 17. Qxc3 Rxe4+ 18. Kf1 Ba6 19. Kg1 Bxd4 -+

  1. 13. Nxd5, this was the move played and the one I was actually expecting. 13. … cxd5, but not exd5 due to the in-between move, Nxe7+ 14. Nc3 e4 15. Bb5


15. Be2 f4 16. Qg6 Rf6 17. Qh5 Rf5 18. Qg4


18. Qh3 [  best ] Rg5 19. Qh4 [  19. g4 followed by either fxg3 or f3 good. -+ ] Rxg2 [  19. … f3 best and Nc6 also good ] 20. Qxf4 Bc5 -/+ [ -+ 20… Rxf2 best ]  


18… h5 19. Qh3 Rg5 [  19… f3 better ] 20. g4


20. Qh4 Rxg2 [  20… f3 best ] 21. Qxf4/h5 =/+ [ 21. Qxf4 best in this line, -+. 21. Qxh5 bad due to Rg5 ]


20… fxg3 [  20… f3 still best ] 21. Qf1 [  ??, best 21. Qg2 gxf2+ -+ ] gxf2+ =/+ [ ?, -+ but better is 21… g2 ]


15. … f4 (here white resigned) 16. Qg6 [  -+ ]. Now if 16. … Rf6, white has the option of Qe8+, offering the queen trade or a potential repetition of position in case of Rf8, Qg6. Another option is to follow the Qh5 lines in the above variations, probably maintaining equality. Overall I still think black only has a slight advantage, mostly in space, though the white squares around the king are also weak. =/+ [ -/+ in the 17. Qe8+ line ]

I believe this is the best line for black.

Another line here, would be 14. … f4 immediately. I debated this move for a little while but thought white would trade out in the center and then castle. For example: 15. Qf3 e4 [  15… Be6 best -/+ ] 16. Nxe4 dxe4 17. Qxe4 [ ?? -+ ] with an attack on h7. Though, after 17. Qxe4, Bf5 looks pretty good for black [  best, with 18. Qf3 or Qe3 followed by 18… Bxd3 -+ ]. Qxf4 and Bxe3 attacking the queen wins a piece for black -+.

So, 18. Bxe4 looks better leaving  black with Rb8 as the only move =+.


  1. 14. O-O [ best ] fxe4 [ Nf4 or Nb4 better ? ] 15. Bxe4. Now black has a weakness on e5 and the black pieces need to have better coordination. At this point I evaluate the position as = and maybe +/= [  -+ ].  Maybe 15. … Bf6 would be good but after d3 or Re1 I think white is fine. [  -/+, a lot of slightly better moves ]

  2. 14 b3.This gets white’s black squared bishop a chance at some activity. 14. … fxe4 15. Bxe4 [  15. Nxe4 best -+ ] and black has some of the same problems as in C. Maybe 15. … Bc5 16. O-O +/= or = [ -+, 16. f3 better ].

  3. 14. Be2 fxe4 and now either Nxe4 or even Qxe5 as the e4 pawn is just hanging +/= or = [ -+ ].


That was the end of my exercise. My final thoughts will be in the next blog.
